Lincoln Electric SA-250 manual PRE-OPERATION Service, Polarity Control and Cable Sizes, Oil, Fuel

A-3 INSTALLATION A-3

•Design capacity of trailer vs. weight of Lincoln equipment and likely additional attachments.

•Proper support of, and attachment to, the base of the welding equipment so there will be no undue stress to the framework.

•Proper placement of the equipment on the trailer to ensure stability side to side and front to back when being moved and when standing by itself while being operated or serviced.

•Typical conditions of use, i.e., travel speed, rough- ness of surface on which the trailer will be operat- ed; environmental conditions, likely maintenance.

•Conformance with federal, state and local laws. (1)

(1)Consult applicable federal, state and local laws regarding specific requirements for use on public highways.

POLARITY CONTROL and CABLE SIZES

With the engine off, connect the electrode and work cables to the studs located on the fuel tank mounting rail. (See size recommendations below.) For positive polarity, connect the electrode cable to the terminal marked “+”. For Negative polarity, connect the elec- trode cable to the “-”stud. These connections should be checked periodically and tightened if necessary.

When welding at a considerable distance from the welder, be sure you use ample size welding cables.

RECOMMENDED COPPER CABLE SIZES

			Cables Sizes for Combined Length
			of Electrode Plus Work Cable
	Amps	Duty Cycle	Up to 200 ft.	200 to 250 ft.
250		100%	1	1/0
300		60%	1/0	2/0

OIL

This unit is supplied from the factory with the engine crankcase filled with a high quality SAE 10W/30 oil. This oil should be acceptable for most typical ambient temperatures. Consult the engine operation manual for specific engine manufacturer’s recommendations. Upon receipt of the welder, check the engine dipstick to be sure the oil is at the “full” mark. DO NOT overfill.

FUEL

Fill the fuel tank with the grade of fuel recommended in the Engine Operator’s manual. Make sure the fuel valves on the sediment bowl and the water separator are in the open positions.

COOLING SYSTEM

The radiator has been filled at the factory with a 50-50 mixture of ethylene glycol antifreeze and water. Check the radiator level and add a 50-50 solution as needed (see engine manual or antifreeze container for alternate antifreeze recommendations).
